This HiRISE image is located North of Meridiani Planum near the landing site of the Mars Exploration Rover Opportunity.

The surface adjacent to the edge of the crater is characterized by light-toned, regularly layered sedimentary rock, dark-toned material trapped in degraded crater floors, and knobs. The layered rocks are faulted (offset) in places and folded (see inset of false color image, 1 kilometer/0.6 miles across).
